WikidPad

WikidPad is a wiki-like notebook for storing your thoughts, ideas, to-do lists, contacts, or anything else you can think of to write down. What makes wikidPad different from other notepad/outliner applications is the ease with which you can cross-link your information. Links in a wiki are created by typing in WikiWords. A WikiWord is any mixed case word typed into the editor. To-do List or JohnDoe are example WikiWords. The term wiki means 'quick' in Hawaiian, and wikidPad is all about quickly linking your information together. Features include on the fly WikiWord linking, auto-completion, attribute based document indexing, incremental search, text styling, export to HTML, auto-save.
